Good option for city riding
Used for 1 week or less
Light is good and visible from 10 to 15 ft away, if light has more lumens then it could be more better and problem with this light is fixed strap is very tight for seatpost, no instruction manual given in blister pack (how to charge). if you are riding more than 25 kms i will recommend you to get extra 1 more light for backup in night because rear light is really very necessary on roads to get visible easily by big and small vehicles for safety.
Initial Impressions - Value for money
Used for 1 week or less
Its have been just 3 days that I started using this product. The light is bright enough. Just one question - How do I come to know when the light is fully charged? When I connect the light to my laptop, the red light blinks. I assume the blinking indicates charging but the blinking never stops even after an hour.
Awesome

Battery back up is 3-5 hrs. It's very good as an indicator light on road but can't use as light or powerful source of light to view the road conditions.
Great Product

I bought this as a rear light for my wife's bike. It's very good and visible from a long distance. I'm sure it can be used as a front light too when needed. Great product. Highly recommended.
Top bit of kit

The light is very versatile as it can switch from red to white. It has an adequate power for town use and lasts long enough in flash mode.Its very compact and easily fits in your pocket or bag to carry around, charging is easy from any USB outlet.
I have not noticed any water ingress problems so far as others have mentioned.
Its a great light at a very competitive price.
Not waterproof or reliable!!!
Used for 2 to 8 weeks
Bought this as a replacement for VIOO 300 light but it has the same inherent faults - after being used for a rainy ride it has now gone haywire, after charging up it won't switch on properly, then won't switch off and now it's switched on on it's own and won't go off. Yet another light I'm returning to Decathlon, these are useless.
Ok when it worked
Faulty after using in the rain
Response of the brand
Hello,

Thank you for your review of this product, I will forward you're feedback onto the product manager. If you could let me know how bad the rain was which affected the light that would be great.

Useful and effective, it's rather better as a rear-facing fixed or flashing light rather than showing the way forward. Its rigid structure means that it doesn't sit too comfortably around a square post, but that is not a major issue.
Good rear visibility
